Detailed Description
The electronic equipment with the drawable display screen is characterized in that a display screen part of the electronic equipment is arranged on the front side of the electronic equipment and is used for displaying in a conventional mode, and the other part of the display screen is curled in the electronic equipment or on the back side of the electronic equipment in the conventional mode, so that the portability of the electronic equipment can be improved. When another part of the display screen is pulled to the front of the electronic device, the part of the display screen is flattened and can be used for displaying. At this time, the display screen area of the electronic device increases, and large-screen display of the electronic device can be realized. However, to enable another part of the display to be switched between a rolled-up state and a flattened state, the part of the display is often configured in a free state, i.e. it is not connected to a stationary part inside the electronic device. The part of the display screen is easy to be pressed to sink and even can not be flattened because of no reliable mechanism for supporting the part of the display screen. In order to solve the problem that such a display screen is pressed and sinks, a movable supporting structure is arranged below the display screen and used for supporting the display screen, however, in order to enable the supporting structure to move, a certain gap is reserved between the supporting structure and the display screen, so that a pressing virtual position is formed below the part of display area, and the user experience is affected.
Therefore, the application provides a shell assembly for supporting a display screen and electronic equipment with the shell assembly, so as to solve the problems of poor display effect and poor user experience caused by the fact that a virtual pressing position is formed below the display screen, and the display screen is pressed to sink.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
As shown in fig. 1, fig. 1 is a schematic structural diagram of an electronic device 100 according to an embodiment of the present application. The electronic device 100 provided by the application can be various devices with a rollable display screen, such as a mobile phone, a tablet, an electronic reader, a computer, an electronic display screen and the like. The embodiments of the present application will be described with reference to a mobile phone having a rollable display screen. For convenience of description, the following embodiment defines the thickness direction of the electronic device 100 as the Z-axis direction, and the direction indicated by the arrow is the forward direction.
The electronic device 100 comprises a housing assembly 1 and a display screen 2. The housing assembly 1 and the display screen 2 are arranged along the Z-axis direction. The side of the display 2 facing away from the housing assembly 1 is referred to as the front side of the electronic device 100, which is oriented in the forward direction of the Z-axis. The side of the housing assembly 1 facing away from the display 2 is referred to as the back side of the electronic device 100, which is opposite to the Z-axis.
Referring to fig. 1 to 3, the display 2 may be a flexible display 2. The display screen 2 includes adjacent first and second display sections 20 and 21. Specifically, the first display unit 20 and the second display unit 21 correspond to different display areas on the display screen 2. It will be appreciated that the first display portion 20 and the second display portion 21 are different display areas on the same display screen 2.
Referring to fig. 1 and 2, when the display 2 is in a curled state, the first display portion 20 is disposed on the front surface of the electronic device 100; the second display portion 21 is curled inside the electronic apparatus 100, or the second display portion 21 is curled on the back surface of the electronic apparatus 100. When the display 2 is in the curled state, the first display portion 20 may be used for display, and the second display portion 21 may be used for display or not. The display 2 being in a curled state is understood to mean that the entire display 2 is U-shaped.
Referring to fig. 1 and 3, when the display 2 is in the flattened state, the first display portion 20 is disposed on the front surface of the electronic device 100, and the second display portion 21 is at least partially disposed on the front surface of the electronic device 100, that is, the second display portion 21 is partially or entirely disposed on the front surface of the electronic device 100. At this time, the second display portion 21 provided on the front surface of the electronic apparatus 100 is flush with the first display portion 20. When the display screen 2 is in the flattened state, both the first display portion 20 and the second display portion 21 can be used for displaying.
Referring to fig. 4 to 6, the housing assembly 1 includes a first housing 10, a second housing 11 and an abutment assembly 12.
Wherein the first housing 10 comprises a first support surface 101. The first supporting surface 101 is used for supporting the first display portion 20. Specifically, the first display portion 20 is fixed to the first supporting surface 101 of the first housing 10. In one embodiment, the first display portion 20 is adhered to the first supporting surface 101.
Referring to fig. 4 and 5, the second housing 11 is slidably connected to the first housing 10, and the second housing 11 can be extended and retracted relative to the first housing 10. Specifically, the second housing 11 is retractable in the X-axis direction with respect to the first housing 10. The X-axis direction is the arrangement direction when the first display unit 20 and the second display unit 21 are aligned.
As shown in fig. 4, when the display screen 2 is in the flattened state, the second display portion 21 is at least partially aligned with the first display portion 20 along the X axis, and the second housing 11 partially or entirely protrudes with respect to the first housing 10. At this time, the second housing 11 is in the extended state.
As shown in fig. 5, when the display screen 2 is in a curled state, the second display portion 21 is curled at least partially inside the electronic apparatus 100 or curled at the back of the electronic apparatus 100, and the second housing 11 is partially or fully retracted with respect to the first housing 10. At this time, the second housing 11 is in the retracted state.
Referring to fig. 6 and 7, the second housing 11 has a second supporting surface 110 and an abutting surface 112 disposed opposite to each other. Specifically, the second supporting surface 110 and the abutting surface 112 are disposed opposite to each other along the Z-axis direction. The second support surface 110 faces the front of the electronic device 100. The abutment surface 112 faces the back surface of the electronic device 100. In other words, the second support surface 110 is forward toward the Z-axis. The abutment surface 112 is reversed toward the Z axis.
As shown in fig. 7, when the second display portion 21 is in the flattened state, at this time, the second housing 11 is in the extended state, and the second display portion 21 is supported on the second support surface 110 of the second housing 11 and is flush with the first display portion 20. In other words, the second support surface 110 of the second housing 11 is in contact with the second display portion 21. It will be appreciated that when it is desired to increase the area of the display 2, the second display portion 21 may be at least partially flattened to be flush with the first display portion 20, and at this time, both the first display portion 20 and the second display portion 21 may be used for display. The second display portion 21 is supported on the second supporting surface 110 of the second housing 11, so as to avoid the pressing virtual position formed at the lower portion of the second display portion 21 when the large screen is in use.
As shown in fig. 8, when it is necessary to reduce the area of the display screen 2 for portability, the second housing 11 can be put in a retracted state by curling the second display portion 21, and the overall size of the electronic apparatus 100 can be reduced, achieving portability.
Wherein the expansion and contraction of the second housing 11 with respect to the first housing 10 and the curling or flattening of the second display portion 21 with respect to the first display portion 20 may be synchronized. Specifically, the second display portion 21 is gradually flattened with respect to the first display portion 20 while the second housing 11 is gradually protruded with respect to the first housing 10. The second display portion 21 gradually curls with respect to the first display portion 20 while the second housing 11 gradually retracts with respect to the first housing 10. Of course, the expansion and contraction of the second housing 11 with respect to the first housing 10 and the curling or flattening of the second display portion 21 with respect to the first display portion 20 may be asynchronous. For example: after the second display portion 21 is flattened, the second housing 11 is extended with respect to the first housing 10 so that the second supporting surface 110 supports the second display portion 21. After the second housing 11 is retracted with respect to the first housing 10, the second display portion 21 is curled with respect to the first display portion 20.
Referring to fig. 7 and 8, the abutment assembly 12 is disposed on a side of the abutment surface 112 of the second housing 11 facing away from the second supporting surface 110 of the second housing 11. It can be appreciated that the abutment assembly 12 is disposed on a side of the second housing 11 away from the display screen 2, that is, the display screen 2, the second housing 11, and the abutment assembly 12 are sequentially arranged along the Z-axis direction. The abutment assembly 12 is configured to abut against an abutment surface 112 of the second housing 11 when the second housing 11 is in the extended state, and to make the second supporting surface 110 contact and support the second display portion 21. In other words, the abutment assembly 12 is configured to level the second display portion 21 with the first display portion 20 when the second display portion 21 is aligned with respect to the first display portion 20.
It will be appreciated that, as shown in fig. 7, when the second housing 11 is in the extended state, the second support surface 110 is at least partially in contact with the second display portion 21. At this time, the second supporting surface 110 is flush with the first supporting surface 101 along the Z-axis direction; alternatively, when the adhesive layer is disposed between the first display portion 20 and the first supporting surface 101, the second supporting surface 110 is flush with a side of the adhesive layer, where the first display portion 20 is connected, in the Z-axis direction. For the entire electronic apparatus 100, the first supporting surface 101 supports the first display portion 20 and the second supporting surface 110 contacts and supports the second display portion 21 when the second housing 11 is in the extended state. As shown in fig. 8, when the second housing 11 is in the retracted state, the first support surface 101 supports the first display portion 20, and the second display portion 21 is curled. The second supporting surface 110 faces the first display portion 20, and has a gap with the first display portion 20.
As shown in fig. 7, it can be understood that the abutment assembly 12 acts an abutment force on the second housing 11 through the abutment surface 112 when the second housing 11 is in the extended state. In one embodiment, the abutment force of the abutment assembly 12 on the second housing 11 is equal to the self weight of the second housing 11. By making the abutment force of the abutment assembly 12 against the second housing 11 equal to the self weight of the second housing 11, the balance between the second housing 11 and the abutment assembly 12 in the Z-axis direction can be maintained, so that the second support surface 110 can stably support the second display portion 21. In another embodiment, the abutment force of the abutment assembly 12 on the second housing 11 is greater than the self weight of the second housing 11. By making the abutment force of the abutment member 12 on the second housing 11 larger than the self weight of the second housing 11, the second housing 11 can have a certain bearing force against the second display portion 21, and thus the second display portion 21 can receive a certain pressing force under the support of the second support surface 110.
By making the first supporting surface 101 of the first housing 10 support the first display portion 20 of the display screen 2, and making the second supporting surface 110 of the second housing 11 contact and support the second display portion 21 when the second housing 11 extends relative to the first housing 10, it is ensured that the first display portion 20 and the second display portion 21 have higher strength and rigidity when the display screen 2 is in use, so that the display screen 2 is prevented from being pressed to sink, and the use effect is prevented from being affected. In addition, the second display portion 21 is flush with the first display portion 20 under the support of the second support surface 110, so that a drop between the first display portion 20 and the second display portion 21 can be avoided, and the experience of the user can be improved.
As shown in fig. 9, alternatively, the abutment surface 112 includes a first sub-abutment surface 112a and a second sub-abutment surface 112b arranged in the direction in which the second housing 11 expands and contracts. The direction in which the second housing 11 expands and contracts is referred to as X direction in the figure. The distance between the first sub-abutment surface 112a and the second support surface 110 is smaller than the distance between the second sub-abutment surface 112b and the second support surface 110. In other words, the thickness of the second housing 11 at one end in the X-axis direction is smaller than the thickness at the other end.
As shown in fig. 9, when the second housing 11 is in the extended state, the abutment assembly 12 abuts the second sub-abutment surface 112b. As shown in fig. 10, when the second housing 11 is in the retracted state, the abutment assembly 12 contacts the first sub-abutment surface 112a, or the abutment assembly 12 is spaced apart from the first sub-abutment surface 112a.
In other words, the position of the second housing 11 opposite the abutment assembly 12 is switched from the first sub-abutment surface 112a to the second sub-abutment surface 112b during the process from the retracted state to the extended state. It will be appreciated that during the process of the second housing 11 from the retracted state to the extended state, the second supporting surface 110 gradually moves toward the display screen 2 in the Z-axis direction until the second supporting surface 110 contacts and supports the second display portion 21 when the second housing 11 is in the extended state.
In one embodiment, as shown in fig. 10, when the second housing 11 is in the retracted state, the abutment assembly 12 contacts the first sub-abutment surface 112a. Specifically, when the second housing 11 is in the retracted state, no or little force is applied between the abutment assembly 12 and the second housing 11 in the Z-axis direction. At this time, a gap is formed between the second supporting surface 110 and the display screen 2, which is favorable for the extension and retraction of the second housing 11. In addition, the second supporting surface 110 and the display screen 2 have a gap, so that friction between the second shell 11 and the display screen 2 in the extending process can be avoided, and the service life of the display screen 2 is reduced.
In another embodiment, as shown in fig. 11, when the second housing 11 is in the retracted state, the abutment assembly 12 is spaced apart from the first sub-abutment surface 112a, i.e. a gap is provided between the abutment assembly 12 and the first sub-abutment surface 112a. In this embodiment, in the expansion and contraction process of the second housing 11, a gap is formed between the second supporting surface 110 and the display screen 2, and a gap is formed between the abutting surface 112 and the abutting component 12, so that the friction force applied in the expansion and contraction process of the second housing 11 can be reduced, which is beneficial to the expansion and contraction of the second housing 11. When the second housing 11 is in the extended state, the abutment force of the abutment assembly 12 acting on the second housing 11 through the second sub-abutment surface 112b is greater than or equal to the self weight of the second housing 11, so that the second support surface 110 can be ensured to support the second display part 21. When the contact force of the contact unit 12 to the second housing 11 via the second sub-contact surface 112b is greater than the weight of the second housing 11, the second display portion 21 can be supported by the second support surface 110 and can receive a predetermined pressing force.
By bringing the abutment member 12 into contact with the first sub-abutment surface 112a when the second housing 11 is in the retracted state, or by bringing the abutment member 12 into contact with the second sub-abutment surface 112b when the second housing 11 is in the extended state, the abutment member 12 can contact with and support the second display portion 21 while ensuring that the second housing 11 is in the extended state, and expansion and contraction of the second housing 11 are facilitated.
Further, as shown in fig. 11, the abutment surface 112 further includes an inclined surface 112c. The inclined surface 112c is provided between the first sub-contact surface 112a and the second sub-contact surface 112b. In other words, in the X-axis direction, the abutment surface 112 includes a first sub-abutment surface 112a, an inclined surface 112c, and a second sub-abutment surface 112b that are sequentially connected. It is understood that the inclined surface 112c is connected between the first sub-abutment surface 112a and the second sub-abutment surface 112b, and the inclined surface 112c extends along the X-axis direction. In the process of the second housing 11 from the retracted state to the extended state, the abutment assembly 12 is first contacted or spaced from the first sub-abutment surface 112a, and as the second housing 11 is extended, the abutment assembly 12 is contacted with the inclined surface 112c until the abutment assembly 12 abuts against the second sub-abutment surface 112b.
By providing the inclined surface 112c between the first sub-abutment surface 112a and the second sub-abutment surface 112b, the position of the second housing 11 relative to the abutment member 12 can be gradually switched from the first sub-abutment surface 112a to the second sub-abutment surface 112b during expansion and contraction, so that the stability of the second housing 11 during expansion and contraction can be ensured, and the abutment force of the abutment member 12 to the second housing 11 during expansion and contraction, that is, the supporting force of the second support surface 110 to the second display portion 21 can be gradually increased.
Referring to fig. 12 and 13, a chute 102 is disposed on one side of the first supporting surface 101 of the first housing 10. The number of runners 102 may be one or more. The second housing 11 includes one or more support plates 113. Alternatively, when the number of the sliding grooves 102 is one, the number of the supporting plates 113 of the second housing 11 is one, and the supporting plates 113 slide in the sliding grooves 102. When the first housing 10 is provided with a plurality of sliding grooves 102, the sliding grooves 102 are arranged at intervals, and accordingly, the number of the supporting plates 113 of the second housing 11 is plural, and the plurality of the second supporting plates 113 slide in the corresponding sliding grooves 102 respectively. The slot wall of the slot 102 includes a bottom surface 102a, a first side surface 102b adjacent to the bottom surface 102a, and a second side surface 102c adjacent to the bottom surface 102 a. The bottom surface 102a of the chute 102 is spaced apart from the first display portion 20. One end of the first side surface 102b facing away from the bottom surface 102a and one end of the second side surface 102c facing away from the bottom surface 102a form an opening portion of the chute 102. By arranging the sliding groove 102 to enable the second housing 11 to slide in the sliding groove 102, the thickness of the electronic device 100 along the Z-axis direction can be reduced, which is beneficial to the light and thin of the electronic device 100 and the space utilization of the electronic device 100.
When the second housing 11 is in the retracted state, a gap is provided between the second support surface 110 and the first display portion 20. A gap is provided between the abutment surface 112 and the bottom surface 102a of the chute 102. Specifically, when the second housing 11 is in the retracted state, the second housing 11 is at least partially located in the chute 102, and at this time, the first supporting surface 101 supports the first display portion 20, and the second supporting surface 110 is spaced from the first display portion 20. The first sub-contact surface 112a, the inclined surface 112c, and the second sub-contact surface 112b are spaced apart from the bottom surface 102a of the chute 102.
When the second housing 11 is in the retracted state, the second supporting surface 110 and the first display portion 20 have a gap therebetween, and the contact surface 112 and the bottom surface 102a of the chute 102 have a gap therebetween, so that friction between the second housing 11 and the display screen 2 and the bottom surface 102a of the chute 102 when sliding along the chute 102 can be reduced, and reliability of sliding of the second housing 11 can be improved.
As shown in fig. 14, the abutment assembly 12 is at least partially disposed within the chute 102. In one embodiment, the abutment assembly 12 is protruded from the bottom surface 102a of the chute 102, i.e. the abutment assembly 12 is entirely disposed in the chute 102. The abutment assembly 12 may be directly fixedly coupled to the bottom surface 102a of the chute 102. In this embodiment, the abutment assembly 12 is protruded on the bottom surface 102a of the chute 102, so as to reduce the difficulty of the process and simplify the assembly steps.
In another embodiment, as shown in fig. 15, the abutment assembly 12 is partially disposed in the chute 102. Specifically, the chute 102 is further provided with a receiving groove 103. The abutment assembly 12 is partially accommodated in the accommodation groove 103 and partially protrudes from the slide groove 102. In this embodiment, the abutting component 12 is partially accommodated in the accommodating groove 103, which is beneficial to reducing the thickness of the housing component 1 along the Z-axis direction.
Optionally, the abutment assembly 12 is resilient. Specifically, the abutment assembly 12 is capable of telescoping or deforming in the Z-axis direction. By providing the abutment assembly 12 with elasticity, the abutment assembly 12 can be elastically abutted against the second sub-abutment surface 112b. When the second supporting surface 110 contacts and supports the second display portion 21, if the force between the second supporting surface 110 and the second display portion 21 is too large, the force of the second housing 11 on the abutment assembly 12 can deform the abutment assembly 12, so as to avoid the second supporting surface 110 from pressing the second display portion 21.
Referring to fig. 16 and 17, the abutment assembly 12 includes an elastic member 120 and a ball 121.
In one embodiment, during the expansion and contraction of the second housing 11, the balls 121 move in a direction perpendicular to the expansion and contraction direction of the second housing 11 under the action of the elastic member 120. Specifically, during the process of the second housing 11 from the retracted state to the extended state, the balls 121 gradually move reversely along the Z axis by the second housing 11. When the second housing 11 is in the retracted state, the balls 121 abut against the first sub-abutment surfaces 112a by the elastic member 120. When the second housing 11 is in the extended state, the balls 121 abut against the second sub-abutment surfaces 112b by the elastic member 120.
In another embodiment, the abutment assembly 12 further comprises a bracket 122. Referring to fig. 16 and 17, the bracket 122 is disposed in the accommodating groove 103. The bracket 122 is surrounded to form a limit groove 123. The ball 121 is limited in the limiting groove 123 and at least partially protrudes out of the bottom surface 102a of the chute 102 to contact or abut against the second housing 11. The elastic member 120 is connected to the bracket 122. During the process of the second housing 11 from the retracted state to the extended state, the balls 121 and the brackets 122 gradually move reversely along the Z-axis by the second housing 11, the elastic member 120 is gradually compressed, and the balls 121 gradually switch from being spaced from or in contact with the first sub-abutment surface 112a to being in contact with the second sub-abutment surface 112b. Specifically, when the second housing 11 is in the retracted state, the support 122 abuts against the groove wall of the accommodating groove 103, the elastic member 120 may be in the original length or the compressed state, and the ball 121 is limited in the limiting groove 123 and contacts the first sub-abutment surface 112a or is spaced from the first sub-abutment surface 112a. As the elastic member 120 is gradually compressed during the process of the second housing 11 from the retracted state to the extended state, the abutment force of the balls 121 against the second housing 11 gradually increases. Until the second housing 11 is in the extended state, the ball 121 acts on the second housing 11 with an abutment force equal to the weight of the second housing 11 by the elastic member 120, and the second support surface 110 of the second housing 11 contacts the second display portion 21 by the elastic member 120. Alternatively, until the second housing 11 is in the extended state, the ball 121 acts on the second housing 11 by the elastic member 120 to have an abutment force greater than the weight of the second housing 11, and the second support surface 110 of the second housing 11 abuts against the second display portion 21 by the elastic member 120 to allow the second display portion 21 to receive a certain pressing force.
In this embodiment, by providing the balls 121, the balls 121 are in contact with the first sub-contact surface 112a or the second sub-contact surface 112b of the second housing 11, and rolling friction is formed between the balls 121 and the second housing 11 in the process of expanding and contracting the second housing 11, so that the friction between the balls 121 and the second housing 11 is small due to rolling friction, and the resistance in the process of expanding and contracting the second housing 11 can be reduced, which is beneficial to expanding and contracting the second housing 11.
As shown in fig. 18, the groove wall of the accommodating groove 103 includes a bottom wall 103a, a first limiting wall 103b, and a second limiting wall 103c. The bottom wall 103a and the first limiting wall 103b face the bottom surface 102a of the chute 102, and the first limiting wall 103b is disposed between the bottom wall 103a and the bottom surface 102a of the chute 102. The second limiting wall 103c is opposite to the first limiting wall 103b, and the second limiting wall 103c is disposed between the first limiting wall 103b and the bottom surface 102a of the chute 102. In other words, the second stopper wall 103c, the first stopper wall 103b, and the bottom wall 103a are arranged in order along the Z-axis direction. The first limiting wall 103b is disposed opposite to the second limiting wall 103c.
Referring to fig. 18 to 20, the bracket 122 further includes an annular extension 122a. The annular extension 122a is disposed around the edge of the limiting slot 123. When the second housing 11 is in the retracted state, the annular extension 122a abuts against the second limiting wall 103c under the action of the elastic member 120. At this time, under the limiting action of the second limiting wall 103c, the elastic member 120 may be in a compressed state, and the ball 121 contacts the first sub-abutment surface 112a or is spaced apart from the first sub-abutment surface 112a. When the second housing 11 is in the process of moving from the retracted state to the extended state, as the elastic member 120 is gradually compressed under the action of the second housing 11, the support 122 gradually moves reversely along the Z axis under the driving of the elastic member 120, and the annular extension 122a moves toward the first limiting wall 103b until the annular extension 122a abuts against the first limiting wall 103b, the abutment force of the elastic member 120 on the second housing 11 is equal to the dead weight of the second housing 11, and the second supporting surface 110 of the second housing 11 contacts the second display portion 21 under the action of the elastic member 120. Alternatively, until the annular extension 122a abuts against the first limiting wall 103b, the abutment force of the elastic member 120 acting on the second housing 11 is greater than the self weight of the second housing 11, and the second supporting surface 110 of the second housing 11 abuts against the second display portion 21 under the action of the elastic member 120, so that the second display portion 21 can bear a certain pressing force.
By providing the annular extension 122a on the bracket 122, when the second housing 11 is in the retracted state, the annular extension 122a abuts against the second limiting wall 103c, and the elastic member 120 is compressed in the accommodating groove 103, so that stability of the elastic member 120 is maintained. In addition, the elastic member 120 is compressed in the accommodating groove 103, which is also beneficial to realizing that when the second housing 11 is in the retracted state, the ball 121 only contacts the first sub-contact surface 112a, so as to reduce the contact force acting on the second housing 11 through the first sub-contact surface 112a, avoid the second housing 11 sliding along the Z-axis direction during the expansion and contraction process, and reduce the stability of the expansion and contraction of the second housing 11.
Further, as shown in fig. 21, the housing assembly 1 further includes a driving mechanism 13. The drive mechanism 13 may be an electric motor, a magnetic member, or the like. The driving mechanism 13 is connected to the second housing 11, and the driving mechanism 13 is used for driving the second housing 11 to stretch and retract relative to the first housing 10. Further, the driving mechanism 13 is rotatably connected to the second display section 21. The driving mechanism 13 is used for driving the second display portion 21 to be flattened relative to the first display portion 20 when the second housing 11 is driven to extend relative to the first housing 10. The driving mechanism 13 is further configured to drive the second display portion 21 to curl with respect to the first display portion 20 when the second housing 11 is driven to retract with respect to the first housing 10. By providing the driving mechanism 13 to connect the second housing 11 and the second display portion 21, the second housing 11 can be driven to expand and contract, and the second display portion 21 can be flattened or curled, thereby realizing automation of the electronic apparatus 100. When the driving mechanism 13 drives the second housing 11 and the second display portion 21 simultaneously, the second support surface 110 of the second housing 11 contacts and supports the second display portion 21 while the second display screen 2 is flattened, so as to reduce waiting time when a user uses the electronic device 100 and improve experience of the user.
The foregoing is a partial embodiment of the present application and it should be noted that, for a person skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.
